Air Bag Control Module: Testing and Inspection

Inflatable Restraint Sensing and Diagnostic Module Programming and Setup

Note: The air bag indicator light may remain ON after the body control module (BCM), or inflatable restraint sensing and diagnostic module (SDM) is replaced, and during the programming procedure for the BCM until after the procedure is completed. When installing a new SDM, there may be several DTCs set prior to programming. Once programmed, these DTCs should be in history and can be cleared.

The following service procedures require either a programming or a setup event performed for a complete repair:

Sensing and Diagnostic Module Replacement or Reprogramming

If the sensing and diagnostic control module (SDM) is replaced or needs to be reprogrammed, programming must be performed. Refer to Service Programming System (SPS) (Service Programming System (SPS)). Ensure the following conditions exist in order to prepare for module programming:

1. The battery is fully charged.
2. The ignition switch is in the RUN position.
3. The Techline equipment cable connection at the data link connector (DLC) is secure.
4. Program the control module using the latest software matching the vehicle. Refer to up-to-date Techline equipment user instructions.

If the control module fails to program, proceed as follows:

1. Ensure the DLC and APM connections are good.
2. Inspect the Techline equipment for the latest software version.
3. Attempt to program the control module. If the control module still cannot be programmed properly, replace the control module.

Sensing and Diagnostic Module Setup

The replacement of some components will require a setup procedure for complete repair. The SDM Setup Procedure must be performed if any of the following components are replaced:

1. SDM
2. BCM

Refer to Service Programming System (SPS) (Service Programming System (SPS)) for SDM Setup.
